How do I write/build query using "qf" parameter of dismax handler for my use case?

[Gnanakumar <gn...@zoniac.com>]

Hi,

How do I write/build a Solr query using dismax handler for my application
specific use case explained below:

Snippet of fields definition from schema.xml:

<field name="documentid" type="string" indexed="true" stored="true"
required="true" />
<field name="companyid" type="long" indexed="true" stored="true"
required="true" />
<field name="textfield1" type="text" indexed="true" stored="false"
required="true" />
<field name="textfield2" type="text" indexed="true" stored="false"
required="true" />
<field name="textfield3" type="text" indexed="true" stored="false"
required="true" />

<uniqueKey>documentid</uniqueKey>
<defaultSearchField>textfield1</defaultSearchField>

Now, I want to search for documents containing "solr" and "struts" in all 3
text fields (textfield1, textfield2, textfield3) but within the companyid =
100.

As you can see from above statement, companyid=100 is common here but search
keywords should be searched only in 3 text fields (textfield1, textfield2,
textfield3).

I also understand that this can be written as shown below by qualifying all
the 3 text fields explicitly:
http://localhost/solr/select?q=companyid:100&textfield1:solr AND
struts&textfield2:solr AND struts&textfield3:solr AND struts

But how do I write/build a query using "qf" parameter of dismax query
handler, so that I don't need to specify all the 3 fields explicitly.

Wiki says: "For each "word" in the query string, dismax builds a
DisjunctionMaxQuery object for that word across all of the fields in the qf
param"

NOTE: I'm using "edismax" as my default query type in my Search Handler.

Is it not possible to build query without filter queries "fq"?

For example, something like this (I believe this is syntactically not
correct, but something equivalent to this):
q=companyid:100 AND solr AND struts&qf= textfield1,textfield2,textfield3

Basically, I'm just trying/finding to simplify the query syntax.

edismax supports full query format of lucene parser.But you can search using
filter queries eg.

qf=textfield1, textfield2, textfield3&fq=&textfield1:solr AND
struts&fq=textfield2:solr AND struts&fq=textfield3:solr AND struts
&fq=companyid:100
